Ecologists and evolutionary biologists for many decades happily coexisted largely ignoring each other. This separation was clearest in theory where ecological models assumed fixed, constant parameters, so evolution could not occur, and population genetics models assumed fixed selection coefficients which summarised all underlying ecological process that influence fitness. To an extent this reflected the obvious fact that ecological and evolutionary process occurred on very different time scales – ecology fast, evolution slow.
This has now changed and a large amount of theory now looks at evolutionary dynamics in ecologically realistic models. This led to the idea that evolution need not be slow, and could in fact influence ecological dynamics – the so-called eco-evolutionary feedback. This change in mindset has been accompanied by rapid advances in techniques which now allow high throughput sequencing of species or indeed individuals undergoing ecological interactions – this combined with the “omics” revolution is transforming ecology. This is the dawn of Evolutionary Ecology where ecology and evolution are studied on an equal footing.
In this virtual issue we showcase studies illustrating how diverse studies in Evolutionary Ecology are, and also launch a new Evolutionary Ecology section in Journal of Ecology.
